The paper re-examines the views expressed by Nollkaemper in a paper pu
blished in Marine Policy in November 1993 concerning Agenda 21 and the
prevention of sea-based marine pollution, at the same time as providi
ng an up-to-date account of what has subsequently transpired under the
auspicies of the International Maritime Organisation (IMO) to impleme
nt the outcome of the Rio Earth Summit held in June 1992. The paper co
ntrasts Nollkaemper's predictions as to issues that might be expected
to receive attention in the context of Agenda 21 with actual developme
nts on related issues in IMO over the past five years. Emerging issues
covered by the paper Include incorporation by IMO of the precautionar
y approach and progress made in implementing IMO's strategy for extra
budgetary activities relating to environmentally sustainable developme
nt, covering such issues as the provision of waste reception facilitie
s in ports and capacity-building for coastal states bordering a shalt
used for international navigation. The aim of the latter is to develop
self-sustaining financial mechanisms which would effectively transfer
the cost to the user of the facility, thus eliminating the difficulti
es that many developing countries have in meeting international safety
and environmental standards. Until 1995 the author was cc-ordinator o
f IMO's follow-up to the Earth Summit as a full-time staff member of t
he Organisation's Marine Environment Division. (C) 1998 Elsevier Scien
